Pressure Vessel Design

Hi everyone,

Could anyone explain how to resolve the below presssure vessel design analysis error?

"Computed overall MDMT was higher than required value"

Thanks.

First of all, what is the software that you are using?

A higher computed MDMT means that you have specified a lower MDMT input in your design. You would have to read more on UG-20 and UCS 66 to fully understand this topic. Depending on the situation, you can get away with lower MDMT by doing PWHT, Impact testing, etc. Figure UCS-66.2 provides rules for determining the lowest MDMT permissible without impact testing.
